x41 tablet pen not recognized after activation

Hi, I just installed SUSE 11.1 onto my IBM X41 tablet from a usb version of the Gnome live cd, and I tried activating my tablet pen using SaX2, but after rebooting it still doesn’t recognize the pen (i.e., it doesn’t move when the pen moves across the screen), and the screen buttons don’t work either. Can someone help?
